Undergraduate Students to Present Results of Research at Symposium

WOODS HOLE, MA — The public is invited to attend a symposium featuring the research results of 18 undergraduate students who have spent the fall semester at the Marine Biological Laboratory (MBL) participating in the Semester in Environmental Sciences (SES). The students will present the results of their independent research projects covering topics such as pollution in the coastal zone and consequences of land use changes.  The symposium will be held from 8:30-4:30 pm on Monday, December 15 in the Lillie Auditorium, MBL Street, Woods Hole.

The SES program is sponsored by The Ecosystems Center, the MBL's ecological research arm. Under the instruction of Center's scientists, SES students have been studying aquatic and terrestrial ecosystems science with some of the world's experts on the subject, and attending lectures on biogeochemistry, ecosystems modeling, and global change. They have also participated in a science writing workshop taught by professional science journalists and a seminar series that features
prominent research scientists from around the nation.

Virtually all of the Ecosystems Center's principal investigators and many of the support staff participate in the SES program. Among the key environmental issues studied at The Ecosystems Center are the ecological consequences of global climate change; tropical deforestation and its
effects on greenhouse gas fluxes; nitrogen saturation of mid-latitude forests; effects of acid rain on North American lakes; and pollution and habitat destruction in coastal ecosystems of the United States.

Because the SES program is designed to immerse serious science students in an intensive semester of hands-on ecological science, students spend a significant amount of time in the laboratory and field - 20 hours each week - investigating local forests, ponds, and estuaries.
